PULLING--OVER MACHINE.

Specification of Letters Patent.

Application led June 10, 1908.

Patented May 18, 1909.

Serial No. 437,675.

T o all whom 'it may concern:

Be it known that I, JAKOB ARMBRUSTER, director, German subject, residingat No. 261 Marktstrasse, Soltau, Germany, have invented new and usefulImprovements in Pulling-@ver Machines, of which the following is aspecification.

My invention relates to improvements in pulling over machines of thatclass in which the movable frame holding the last is swung clear of themachine framing about a vertical axis and is then tipped over about ahorizontal axis.

According to the present invention the machine is provided with twinframes, turning about a common vertical axis, while each frame can betilted independently of the other about a horizonatl axis.

The invention is illustrated in the accompanying drawing, in which-Figure l is a side elevation and part section of the machine, Fig. 2 afront elevation of a bottom portion, and Fig. 3 a 4section through thebearing with the horizontal journals of the two frames, drawn to asomewhat larger scale.

The machine has two frames 2, 3 of like construction, so that the last 4can be fixed in either frame for the purpose of lasting the shoe-upper.

The horizontal journal 5 of the frame 2 is mounted in a bearing 7 at thetop ofthe pillar 6 and is hollow, so as itself to act as bearing for thehorizontal journal 8 ofthe twin frame 3. The frames 2 and 3, therefore,can be tipped over on their horizontal journals independently of eachother. The pillar 6, on the other hand, Which presents the bearing 7,serves as common vertical axis of rotation for both frames.

In order to facilitate lifting, by means of the treadle 9, of the framein which the upperleather has been stretched on the last, a spring 10 isfurnished, one end of which rests on the framing l of the machine, whilethe other end bears against a collar 11 on the pillar 6.

To prevent shifting of the horizontal journals of the frames, they areformed with a shoulder, which butts against disks l2 secured in suitablemanner to the bearing 7.

Owing to the provision of twin frames, two hands can work at the samemachine simultaneously. While one operative at the one frame 3 issecuring the stretched upperleather to the insole, the second operativecan be drawing a second upper over the last in the other frame 2.

-Iaving thus described my invention, what I claim as new is 1. In apulling over machine, in combination, a vertical pillar, and twohorizontal lastcarrying frames mounted thereon and capable of beingrotated in a horizontal plane about thc vertical axis of the pillar,each frame having a horizontal j ournal-pin mounted on the pillar, thejournal-pin of the one frame turning inside the journal-pin ci' theother frame, whereby the frames can be independently tilted about theirhorizontal axes, substantially as described.

2. In a pulling over machine, in combination, a vertical spring-actuatedpillar, and two horizontal lastfcarrying frames mounted thereon eachcapable of being turned independently about their horizontal axes andalso of being rotated in a horizontal plane about the vertical axis ofthe pillar, and means for elevating the pillar, substantially asdescribed.

In witness whereof I have hereunto signed my name this 28d day of May1908, in the presence of two subscribing witnesses.

JAKOB ARMBRUSTER.
